Chemical shift effects in nuclear magnetic resonance imaging (NMRI) of adhesives are demonstrated and discussed. The effects of more than one proton resonance on slice selection and on the final image are shown. Relative chemical shift effects are introduced to explain, numerically, how sample size, spectral width, and gradient strengths affect the observed image. The potential and limitations of using chemical shift effects in adhesive studies are discussed with illustrative examples. A model adhesive system was studied which was a typical solventless two-component polyurethane adhesive.

A new two-component polyurethane adhesive was prepared with castor oil used as main agent and castor oil modified TDI used as curing agent.The effect of castor oil on the mechanical properties, adhesion properties and thermal stability of this adhesive were studied.This paper show us that TDI could be used as curing agent after modification. When the NCO/OH in curing agent and main agent:curing agent were 1.6 and 3:5 respectively, high performance adhesive was obtained.
